having been on 2 different types of tours (self guided vs guided), can honestly say Steven has made me like guided tour so much better! we were already impressed with how he's the driver, English guide but he also spoke mandarin fluently, very impressive. I hope he gets paid for doing 3 people's jobs! he was also very knowledgeable about all the places we've been to, and was always providing more info if we asked for it. we deffo learnt more about Korean history through Steven on this tour, which we might not have enjoyed as much otherwise. for improvements wise (nitpicking here), though I liked the pick up service, but since we're the first to be picked up, it felt a bit long winded before we could finally get out of Busan. it wasn't a massive problem for us however, perhaps could consider starting a little earlier otherwise so we could get back without rushing at the end! many thanks for the tour regardless, would recommend!
